Hi there,  So I looked your test app. I'd suggest adding your search results to a different layer and order the features in that layer by their ObjectIds in descending order to ensure that the latest feature is always displayed over other features. You can order the features by setting orderBy property on the layer.  I created this simple codepen app to show how this would work: https://codepen.io/U_B_U/pen/XWzbJbq In this app, I am creating a client-side FeatureLayer as shown below. Notice that I am setting the orderBy parameter to order features by their ObjectIds in descending order. let searchLayer; view.whenLayerView(jsonLayer).then(() =>{ searchLayer = new FeatureLayer({ source: [], copyright: "USU", popupTemplate: jsonLayertemplate, fields: jsonLayer.fields, renderer: jsonLayerRenderer, orderBy: { field: "OBJECTID", order: "descending" }, objectIdField: "OBJECTID", geometryType: "point", }); map.add(searchLayer); });   Then when the search is completed, you add the search result to this layer as shown below. searchWidget.on('select-result',function(event){ layer = event.result.feature.layer; const adds = { addFeatures: [event.result.feature] }; searchLayer.applyEdits(adds); });   I noticed that UniqueValueRenderer you are assigning to your GeoJSONLayer is incomplete. You need to make sure all unique values are included in the renderer. Otherwise, orderBy won't work properly. For example, I had to add general type in the renderer like the following:  { value: "general", symbol: { type: "picture-marker", url: 'https://webdev.usu.edu/map2/images/icons/interest.png', width: '32px', height: '37px' } }, { value: "general building", symbol: { type: "picture-marker", url: 'https://webdev.usu.edu/map2/images/icons/interest.png', width: '32px', height: '37px' } },   Hope this helps, ...

Hi there,  So our documentation is missing the url parameter on imageService.identify. We will get this fixed in the next release. If you are using JavaScript then you can pass  the url as the first parameter (imageService.identify(url, params, options).  You can also add your imageService as a layer then setup a popupTemplate on the layer. Thanks for bringing this issue to our attention.  ... View more

The error indicates that FeatureLayer you creating is a non-spatial FeatureLayer. Meaning that graphics you are adding to the FeatureLayer does not have geometry, just attributes. Is this what you are adding? If you are then you cannot add non-spatial FeatureLayer to the map. Creating a FeatureLayer doc explains how non-spatial FeatureLayers can be used. See under Read more.  If you are creating spatial FeatureLayer then several things to check.  1. You can only add graphics with same geometry types.  2. Are you graphic geometries valid?  3. You should set the FeatureLayer.geometryType in the layer's constructor.  The codepen app sets the params required to initialize FeatureLayer. If you don't then the API will try to infer required parameters from the graphics you pass in and will fail if it cannot infer the params. ... View more

Hi there,  You can do this with the use of Function, Promise or with use of Arcade expressions. This SDK sample shows  how to change the popupTemplate's content dynamically depending on feature attributes. I have modified this sample just a little bit to show images depending on feature attributes. The main logic is in populationChange function.  Simple app: https://codepen.io/U_B_U/pen/dyVEWya?editors=1000 Hope this helps.   ... View more

Hi there,  So the snapshot mode (we load all features on layer load) is enabled when one of the following conditions are met, otherwise layers will fetch its data as needed: If the layer has 0-80,000 points  if the layer has 80,001 - 400,000 points and if the view's initial extent is greater than 10% of layer's data extent (i.e., we are not super zoomed in). Snapshot should be very performant after the initial load. However, if you are making server side calls via refreshInterval or refresh() method, this can slow down the performance as the app has to download the entire data.  Have you considered using client-side filters like FeatureFilter or FeatureEffect on the FeatureLayerView? If you are querying your data also have you considered using client side queries via FeatureLayerView.queryFeatures()? Setting those properties and calling the those methods on the LayerView will take place on the client-side without having to fetch data from the server side.  I created a very simple test app where the layer is loaded in the snapshot mode. I have aded a few buttons where you can set the layer.definitionExpression versus layerView.filter. If you have the network tab open, you'll notice that setting layerView.filter does not generate network requests.  In any case, you can opt of out your layer loading in a snapshot mode by setting featurelayer-snapshot-enabled flag to 0. You can test this flag in the test app I provided by uncommenting the script tag added towards to beginning of the app: https://codepen.io/U_B_U/pen/dyVLKaG?editors=1000 I cannot reproduce the definitionExpression issue you are describing.    ...

Hi there,  Yes sketch creates geometries with a spatial reference that matches the spatial reference of the view. If your basemap's spatial reference is Web Mercator (102100) then you can use webMercatorUtils.webMercatorToGeographic() method to project the geometry to geographic spatial reference.  You can do something like the following.  sketch.on("create", (event) => { if (event.state === "complete") { console.log("sketch geometry", event.graphic.geometry); const geographicGeom = webMercatorUtils.webMercatorToGeographic(event.graphic.geometry); console.log("geographic geometry", geographicGeom) } });   If your basemap's spatialReference is not WebMercator then you can use projection.project() method.   Hope this helps,   ...
